Criminal Investigation Notes

Qincheng is located to the north of Nancheng. It is not trapped by rain or rain. The temperature is three or four degrees lower than that of Nancheng. When he got off the train, Lu Siyu took a deep breath of fresh air and was caught by the cold, sandy wind. Coughing coughing.Compared with the spring in the south, with green trees and lush greenery, here is still a barren, the sky, the earth, people, and the eyes are all dusty, even the accent of people has a kind of dryness, that kind of dryness. It also implies the pungency of a spirit.

Song Wen came to Qincheng for the first time, and felt uncomfortable looking everywhere. The average height of the people here seemed to be higher than that of Nancheng. Fortunately, they were relatively tall, so they were not obtrusive when standing in the crowd.

When I went on a business trip, I couldn’t pay attention anymore. The two of them had a breakfast stall outside the train station. Song Wen ate soy milk fritters, and Lu Siyu ordered a white porridge with a piece of fermented bean curd.

After dinner before going on the road, Lin Wanwan’s home was not in the city, but in a nearby town. Under Lu Siyu’s repeated insistence, they stopped taking the intercity bus, but took a taxi. Tossing all the way, searching the past according to the address, finally came to Lin Wanwan's home.

It was a residential area for a few years, an eight-story building without elevators. Everyone had anti-theft iron fences installed outside their windows. They were of different specifications and looked a bit messy. Clothes of various colors were dried outside the balcony. With the quilt, the corridors are narrow and dark, and there are debris piled up at the door of each house. This style is rare in the south. Fortunately, it is located to the north. Even if the corridors are dark, there is no mold.

Song Wen walked to the door of 403 and knocked on the door. Yesterday he told Zhu Xiao to contact Lin Wanwan's family.Lin Wanwan’s stepfather is a long-distance driver. He is away from home all year round. The destination of this trip is very far. They have to wait four or five days to get home. So they can only make an appointment with Lin Wanwan’s mother and let her be today. Don't go out.

When the door opened, someone looked through the iron gate first, then opened the inside and poked out a woman's head.This is a woman in her forties with a ponytail, but her hair is yellow and sparse. It seems to be due to poor sleep, deep eye sockets, severe dark circles, and a bit deep horoscope pattern. Her clothes are simple and clean. Song Wen saw Lin Wanwan's softness.

Song Wen showed the police officer's card and explained his intentions, and the woman introduced them to the door. The room is not big, but the floor height is not low. This room is not the same as the current popular pattern in the South. There is almost no dining room or living room. It is a place to eat and watch TV, and then there are two rooms, one for adults and one for children.

Lin Wanwan’s mother looked for a cup to pour water for them, and said: “After that happened, I’m worried. My son is still studying and his father is not there. The school teacher said she’s fine, so I I didn’t rush over, but I remembered not to sleep well.” She opened the cabinet as she said, “Oh, my memory, where did the tea leaves...”

Hearing this, Song Wen slightly pursed his lips and exchanged glances with Lu Siyu. He originally thought that Lin Wanwan's parents did not come because of a bad family relationship, but listening to this woman's caring tone did not seem to be fake.Song Wen saw that the woman was still squatting in the kitchen looking for tea, and said, "Auntie, don't be so polite. Let's sit for a while and leave, just to understand Xia Wanwan's family situation."

Before Lu Siyu came, he also read the information of this woman, whose surname is Wang, and her name is Wang Wenyan. He went to work in a clothing factory in the south in his early years, and later went to work in a supermarket here, and stayed at home for the past two years.

After listening to Song Wen's words, Wang Wenyan didn't feel entangled. She brought two glasses of clear water to Song Wen and Lu Siyu, poured herself a glass, and sat on the stool opposite the sofa.

As usual, it was Song Wen’s questioning. Lu Siyu opened the book record. Song Wen first went through the process and asked some basic information, family members’ age, work, etc., and then cut to the topic: "Auntie, can you tell me about your daughter’s basics? Situation?"

Wang Wenyan opened the mouth and said: "My Wanwan is a good boy. Ever since I was young, I haven't made adults worry about it. When I was in school, I studied well and was well-behaved. It's just that I'm not good..."

Having said that, she sighed and seemed to recall her unfortunate marriage: "My ex-husband’s family is more traditional and a bit patriarchal. After I got married, women can’t eat at ordinary times. Wanwan was born. At that time, my mother-in-law was unwilling to say that I was a money-losing guy, and his son was a three-generation single pass, and he was going to be cut off when he came to me. At the time, I ate porridge for a month during confinement. At that time, I lost my weight to eight. Ten catties, I was almost depressed. Later they wanted to force me to divorce my ex-husband, let my ex-husband marry a certain woman and give them a son. At that time, I couldn’t think of not wanting to divorce, so I put my daughter there in anger. Go out to work."

When Wang Wenyan mentioned Lin Wanwan, there was a kind of pride in her tone that could not be concealed, but she also had a trace of debt.

"Then when Lin Wanwan was at your ex-husband's house, who was the main one to take care of her?"

"It's mainly my mother-in-law. She is a woman with a knife-mouthed tofu heart. Although her mouth is not forgiving, she still takes care of Wanwan in behavior." Wang Wenyan rubbed her hands, "That family is a bit oppressive. There are many rules and levels in the family. Wan Wan’s grandfather is the head of the whole family. The old man is very strict and has a lot of tutors, and there is no room for sand in his eyes. Wan Wan’s father has a violent temper and sometimes beats his children when he is angry."

This is a traditional family, patriarchal, with a distinct class. In the home, women are responsible for most of the housework and labor, men are in charge of major events, and domestic violence occurs from time to time. A young girl suddenly loses her mother’s care. In his family, although Wang Wenyan didn't give a specific description, it was enough to remind people of what he had experienced.

Song Wen frowned slightly: "Lin Wanwan was still very young then? Didn't you feel bad about leaving your daughter?"

Wang Wenyan nodded: "My own baby is naturally distressed. When Wan Wan was ten years old, I finally wanted to drive away and divorced that man."

"So during that time, were you and your daughter living together?"

"It was a bit difficult during that time. It is not too much to say that our mother and daughter depended on each other. Two years later, Wanwan graduated from elementary school. According to someone's introduction, I married the man I am now."

Song Wen read the information. Wang Wenyan's current husband, surnamed Li, has a high school diploma, and is a long-distance bus driver. His resume is very simple. He suffers hardships and stands hard work every month, and his salary is always low.

"Later I gave birth to him a son, Wan Wan also grew up, studied well, tried hard, and went to university. It is the pride of our family. Over the years, I have been toward her. Although she is a girl, On my side, I have never been angry." She took her daughter to her side, responsive to requests, and used these as a compensation for her daughter’s childhood misfortune.

"After Lin Wanwan was in junior high school, did you take care of her in her daily life and study?"

"This kid Wanwan is very smart, so I didn’t bother me much. I’m a person, I’ve never accomplished anything since I was a child, I don’t learn well, and I don’t have long-term ability to do a lot of things. I don’t know what to do, and I marry when I meet a man. I often say to Wanwan, “You must never become a person like your mother. You have to have a better life.”

Speaking of the topic of educating children, Wang Wenyan suddenly found the topic. For a housewife like her, children are her best report card, especially if there is a daughter who is as obedient and good as Wan Wan, how many people envy Not coming.Her ordinary life also had shining points and something to be proud of.

Song Wen continued to ask: "After Wanwan goes to college, doesn't she go home often?"

Wang Wenyan’s interest in being provoked was dimmed. She stroked her hair with her hand to ease her embarrassment: “She is very busy with her studies and is still working outside. We pay for the tuition, but not much for living, but As long as she says she is short of money, we will call her." Then she sighed, "It would be shameful to have mediocre parents like us."

"Have Lin Wanwan said, how is her life at school, and how is the relationship with the classmates in the dormitory?"

"Wan Wan said that she was very good at school. The teachers and classmates took good care of her. I saw several children in their dormitory when they gave Wan Wan things. They all seemed to be good kids. How could..." Wang Wenyan sighed a little regretfully, "I remember there was a child in it who was tall and beautiful, and then there was one who was quite white and looked good at home."

"She also has a classmate called Guo Wei, have you seen it?"

"I also have an impression of the child named Guo, but I haven't heard Wan Wan mention it much." Wang Wenyan said and stroked her hair.

Lu Siyu frowned slightly, thinking about what kind of "friends" Lin Wanwan and Guo Xu were. Before Song Wen could continue to ask, he raised his eyes and looked at the woman's rough hands: "Lin Wanwan was at home at the time. Do you usually do housework when you’re in?"

The woman nodded, as if serving the children and husband at home is a matter of course: "I do all things like cooking, washing dishes, washing clothes and cleaning. The children are busy at school, and my husband is also busy at work and not at home all the time. Earn hard money." Then she sighed, "Comrade police, my stringer is okay. This time, it must be just being linked. She is a well-behaved, obedient and kind-hearted girl."

Lu Siyu recorded this, biting his pen cap and lowering his head to think. Some of the information seemed to be different from the clues they knew before. Although Lin Wanwan had a bad background, she was actually a poor girl, and the abuse and harshness she suffered seemed to be All before her ten years old.

Song Wen asked some more regular questions. Wang Wenyan answered them one by one. After seeing that it was almost half past ten, Song Wen got up and said, "Can we take a look at Lin Wanwan's stuff?"

Wang Wenyan led them to the children's room. There were two beds in it, one with a guardrail and one without. Obviously, the one with the guardrail was for Lin Wanwan's brother.

The boy was still young, and Lin Wanwan went out for the exam again. There is no room division. There is a cabinet in the room. There are several floors for girls and the other floors for boys. The windows are clearly divided, and Lin Wanwan’s arrangement is neat, but her brother’s is messy, and things can’t fit, but the magic is that even if it’s dirty and messy, his brother didn’t put things on Lin Wanwan. In the space that has not yet been filled.

Wang Wenyan explained: "Wan Wan is not at home now, but we never moved her things, and her brother did not dare to turn over her things."

Song Wen looked at it. There were some books, textbooks, homework books, and a few world masterpieces.

There are dolls in the cabinet. They are the kind of Barbie dolls bought in the mall. There are four or five sets of them. They are glamorous and not in harmony with the style of the whole house. Song Wen saw that there was a box inside. It's the cookie box of the past.He stretched out his hand and opened it. Inside was a box full of chocolate candy papers, colorful and folded like a dancing girl. He once saw Lin Wanwan fold this during interrogation, and raised her head to ask Wang Wenyan: "This is ?"

Wang Wenyan: "This box was brought by Wan Wan when she came over from his father. Although my ex-husband beats and scolds her occasionally, he often buys sweets for her. Later, she came over and occasionally asked me for sweets, and I would buy them too. For her, I saved such a big box."

After reading the bookcase, Song Wen and Lu Siyu rummaged in the room again. The other thing was some old clothes, nothing special.

At this time, the door suddenly banged.

Hearing this voice, Wang Wenyan's face changed, and she ran to open the door in a little panic. As soon as the door lock was opened, someone vigorously knocked it open from the outside, "Mom! Did you forget to put my gym shoes in your schoolbag again? Now?" With the voice, a teenage boy ran in from the outside. He was well-developed, slightly fat, and looked like a little adult.

"There is a physical education class today? Didn't you tell me in advance?" Wang Wenyan stood aside and rubbed his hands a little embarrassingly.

"I said it! I said it a long time ago, and besides, we are at this time every week. School has been open for more than two months. Why don't you remember." The boy ran over and went in and picked up the cold on the table. After a few sips of the cup, I realized that there were more guests at home. He raised his head and looked at Song Wen and Lu Siyu, "What are you doing?"

When Song Wen was about to speak, Wang Wenyan winked at him and said, "It's a teacher from your sister's school. Come to visit and ask about your sister's family.

The boy was Lin Wanwan's younger brother, named Li Zichen, who was nine and a half years old this year. Although the two siblings were born to the same mother, they had different fathers and even had different surnames.Li Zichen rolled his eyes and asked, "What's wrong with my sister?" The boy about ten years old was just when he didn't understand.

Lu Siyu didn't expose Wang Wenyan's lie, and casually rounded up a lie: "There is a quota for exchange students in the school to go abroad. Let's do a home visit."

Li Zichen nodded: "Oh. My sister studies well, the place must be given to her."

Seeing that Li Zichen is here, Wang Wenyan doesn't seem to want to continue to inquire. She brought out a plate with oranges from the kitchen and said: "Anyway, you are back, you will go again later, eat an orange before leaving." , She stuffed the plate in front of the child.

Unexpectedly, this behavior aroused the disgust of the child. He stretched out his hand to push Wang Wenyan, Wang Wenyan's body fell backward, and the oranges on the plate rolled to the ground.

Li Zichen said: "I don't eat oranges. I want my sneakers. I have an appointment with them to play football. You always forget things and don't do anything well. It's so useless. No wonder my sister doesn't want to go home. "He is not at all shy about whether it is a teacher from his sister's school or someone else, standing in the living room sprinkling.

Wang Wenyan sighed, got up and picked up a few oranges, and then went to the balcony to fetch a pair of washed sneakers. Li Zichen stomped his feet and said, "You haven't string the laces yet!"

Wang Wenyan had to sit on the sofa and put on his shoelaces again, and Li Zichen ran back to class contentedly.After sending the child away, Wang Wenyan turned to look at Song Wen and Lu Siyu. She seemed a little embarrassed and said, "This child is all spoiled by me." She laughed as she said, seeming not to feel this at all. It's an embarrassing thing, but a natural normal in life.

Song Wen smiled awkwardly: "The kid."

Seeing that the question was almost done here, the two stood up and left, and came out of Lin Wanwan's house. Song Wen looked at the time: "We still have a while, should we ask the neighbors or something?"

Lu Siyu nodded: "I can't believe what her mother said, there are some doubts in this family..."

When the two people just said this, suddenly an old lady with red cuffs and white hair sprang out from the intersection in front of him. Her eyes were straight, staring at them like a thief: "You two, sneaky. Damn, who is it?"

Song Wen was taken aback by the old lady who appeared suddenly. The old man walked over silently, and suddenly jumped out from behind the wall, his posture extremely dexterous.He hurriedly took out his ID: "We are the police, who came here to search." He looked at the old lady again, "Are you?"

The old lady pointed to her red armband, very proud and confident: "The director of the neighborhood committee in my area, why don't you police come to say hello to our neighborhood committee? Who let you in? This is not compliant!" The old lady said. Jiang Xin Jiang suspiciously took Song Wen's certificate and looked at it. With a strong sense of prevention, he raised his eyes and looked at him, his drooping eyelids were folded four times: "The police in Nancheng, why are we here in Qincheng?"

Song Wen thought to himself, you don’t even have a concierge here, who knows how strict you are. He was patient and simply explained: "Auntie, we have a case in Nancheng. One of the related personnel is related to this side, so come here. For the follow-up, 403 of the three units visited."

"Oh, you go to Lin Wanwan's house." The old lady was obviously very helpful to this aunt, so she returned Song Wen's certificate.

Song Wen and Lu Siyu didn't expect Lin Wanwan to be so famous, they exchanged glances.Song Wen took the credentials back into her pocket and asked her casually: "Yes, it's their home. We just went to see Lin Wanwan's mother. Do you know Lin Wanwan too?"

The old lady said gossiping: "That girl is good at studying, she is famous in our town. This is only a senior year, if it weren’t for her mother’s involvement, the matchmaker would have broken the door. By the way, this girl is out What's the matter?"

Now that the case is still being investigated, Song Wen is unwilling to reveal the details: "She was fine, it was a classmate in Lin Wanwan's bedroom. Let's come over to find out what happened."

"Oh, that's it." The old lady showed a trace of no gossip, a slightly disappointed look, and did not think about why Lin Wanwan had an accident but they came to Lin Wanwan's home for a follow-up.

"Auntie, do you know their family? You said just now that Lin Wanwan was tired by her mother, what's the matter?" Song Wen asked. Generally, such old people walk around the streets and know a lot of news.This time I ran from Nancheng, and it took eight hours on the way back. Some things can only be determined by seeing it with my own eyes.The suspect will lie, and the surrounding parents and relatives will even whitewash the peace.He hopes to hear something different from these neighbors.

The old lady talked about these things in a spirited way: "Oh, yes, that Xiao Wang turned out to be a shelf clerk in this small supermarket. Because he always made mistakes, he was opened later and stayed at home. Speaking of which, this The family has a big fate...It was the winter vacation three years ago. We haven't changed the natural gas here. Every household has gas. Xiao Wang is at home, and Xiao Li did not go out to drive. His second kid is also at home, but Lin Wanwan is at home. I woke up early and went to the library to read and study. Later, the neighbors smelled gas in their home and hurried to call the police. The police, firefighting and first aid came. The family was in a coma and sent to the hospital. I stayed for a few days before I was discharged."

In such a small town, the almost collective death of a family from gas poisoning is big news.

The old lady would still sell her: "Later you guessed what happened. Xiao Wang got up in the morning and boiled the water. But then she felt cold and fell asleep under the bed. The water was boiled to put out the fire, and the family almost let Fortunately, the girl Lin Wanwan had a big life. She went out early in the morning, or she would have to follow the bad luck. But once this happened, no one would come to her door to talk to Wanwan. After all, everyone was afraid of stalling. Go to such a mother-in-law."

Lu Siyu frowned upon hearing this: "Wang Wenyan said this matter?"

The old lady said, "Hey, you still work as a policeman. How can the parties recognize this?"

Song Wen was surprised: "Didn't you say that the police are here? Why didn't the fingerprints be checked? Do an investigation?"

"There are relatives in my family who belong to the Public Security Bureau. At that time, this matter was strange. It was checked. There were no fingerprints, so it was even more surprising. Anyway, Xiao Wang said that she did not boil water, but the water would never come to the gas by itself. His husband Both her sons and daughters agreed that she did it, and she later recognized it. Because there was no death in this matter, so it didn't matter. The gas stove at home was changed to prevent leakage before she dared to continue cooking." The old lady speaks vividly, as if she is the one who handles it, knowing every detail.

This thing is not ordinary. Song Wen frowned, looked back at the direction of the window of Lin Wanwan’s house, and then looked back at Lu Siyu. Lu Siyu lowered his head and bit his nails habitually, as if Thinking about the problem.

Then the old lady wentssiping a few more words and never said anything of value.

In the beginning, the old lady chased them and offered clues. Later, they chased the old lady and wanted to ask about relevant information. The old lady became impatient and looked at her watch frequently, "Oh, I said everything I know. , I have to go shopping to pick up my grandson." Song Wen then let the man go.

Lu Siyu turned his head and looked at Song Wen. Song Wen immediately understood: "Let's go to dinner first, and we must hurry back. We will ask other people what progress there is."

The town is not too big, they chose a small restaurant to sit in, Song Wen ordered food, and Lu Siyu asked someone to warm his take-out food as usual.

It can be seen that Lu Siyu has been forced to a certain extent, and even the food has become short and quick scrambled eggs with tomatoes, chicken, mushrooms, and sea crabs with green onion and ginger.The things are simple to make, but the ingredients are fresh. The tomatoes are peeled off and the sour is sweet. The crabs are also cleaned up. Even the crab clamps are cracked and fried until delicious.The dishes cooked by the chefs in this small restaurant are average, and the portions are not small, but one is more salty. Song Wen finally rubbed the dishes in the Lu Siyu lunch box and ate with rice.

As soon as the meal was finished, Fu Linjiang called.Song Wen plugged in the headphones, used the headset with the headset, and handed the other end to Lu Siyu. Fu Linjiang's voice came: "We have some new discoveries here. We have dinner with Dong Fang and accompanied Dong. It’s not just Ma Aijing who buys things, but Lin Wanwan sometimes. We found a short video of the supermarket downstairs in the school dormitory, where Dong Fang swiped his card, and Lin Wanwan opened the package without seeing the food outside. It's on." They went to the school to check for missing and fill in the vacancies, and all the materials that could be retrieved were retrieved. Sure enough, some details that were not discovered during the initial survey were revealed.

"Also, Ma Aijing did have a leg with their professors, but the professor said that she just asked him to give extra points for his thesis scores. As for the exchange students abroad, Ma Aijing was chosen because the exchange students require good English and good image. Good. Ma Aijing is more in line with this point. They have already told Guo Wei. Guo Wei was very calm and had no objections. Then the paper that Ma Aijing added was co-authored. Guess the other one. Who is the author."

Song Wen guessed: "Lin Wanwan?"

Fu Linjiang exclaimed: "How did you guess it?"

Song Wen snorted: "You made me guess, naturally it is not Dong Fang's, it will never be the cooperation with Guo Wei."

Fu Linjiang also talked about some situations. The main theme was one. Originally, in their reasoning at the crime scene, they felt that Lin Wanwan was outside the dormitory, but now it seems that her relationship with the other people in the dormitory is far Much closer than they initially reasoned.

"Anyway, she spent Dong Fang's money while enjoying the extra points for the thesis that Ma Aijing exchanged for her thesis. She was very comfortable, not at all as pitiful when facing us. And we checked the video. The box of chocolates that day was brought back to the dormitory by Lin Wanwan in the morning. I am also inclined that this matter has nothing to do with Lin Wanwan. She went to the courier to get the chocolates back. She also knew that there was still poison left in Guo Yu's place. There was sufficient time to commit the crime. However, the motive for the murder was still not found."

"Is there any progress in other areas?" Song Wen asked again.

Fu Linjiang said: "The material book is still inspecting the chocolates, but they also encountered problems, and the chocolates didn't write their names. It can only prove that someone once dropped chocolates everywhere. It is impossible to determine who left the traces. "

Song Wen was a little helpless, but he could only accept this kind of result: "Okay, I know these, you guys continue to work hard, wait for me to go back to summarize."

Fu Linjiang hung up the phone, and Lu Siyu took off the headset and said, "I found out before that the relationship in the dormitory may not be as simple as we seem to be on the surface. That day, I felt that Lin Wanwan's place was too clean. Then I figured it out..."

Song Wen thought for a while and immediately understood what Lu Siyu meant: "What we see is what others want us to see. What we ask is what others want us to ask."

After saying this, Song Wen's eyes fell on Lu Siyu, and he remembered the conversation between Zhou Yining and him before.This sentence seems to be suitable for Lu Siyu.

Lu Siyu didn't notice the strangeness in Song Wen's eyes, and lowered his head and said, "We don't know what the real relationship is in the dormitory."

Someone had cleaned up the dormitory. Before the police arrived, perhaps a few days ago, there was a premeditated plan, especially Lin Wanwan's place, which was extremely clean. It was this cleanness that made her look special.

Song Wen sighed and said, "The relationship between these people is more complicated than we thought." This case is different from the cases they have been in contact with in the past.At the beginning, they underestimated the complexity of the case. Looking back, the whole story may be more confusing than they thought.

Two people came out of the small hotel and walked all the way on the streets of a strange city. The roads here are narrower than in the south. The roadsides are full of tall evergreen plants. Now a little bud has just emerged. Song Wen was not in a hurry to take a taxi and turned around. Asked Lu Siyu, "What do you think about Lin Wanwan's family?"

Lu Siyu did not answer Song Wen, blinked his eyes and asked him, "What do you think?"

Song Wen thought for a while: "Lin Wanwan's home is different from what I had imagined before. I thought her parents were indifferent and treated her badly. That's why she developed her gentle character, but I didn't expect her The family is like this. The mother is very fond of her, the stepfather is honest, and he is absent all year round. The younger brother is rude and unreasonable, but he also values ​​the sister. This family seems to be a happy family. But I always feel that something is wrong."

Lu Siyu had a cold expression on his face: "A happy family? A mother with a bad memory, a father who has not been at home all the time, a arrogant younger brother, and an older sister who is suspected of being a murderer. The family was almost killed in one go. Of gas poisoning, this is a model for a horror story."

Song Wen clearly understands a truth. When different people look at the same thing, their perceptions may be completely different. All of this is also related to his life experience. As a criminal policeman, he has always been more than integrity. This integrity can make him more upright. Sticking to his own justice, but it also made him unable to understand the abnormal world in which the criminals were living, unable to penetrate into the dark place and probe their twisted hearts.In short, he is a normal person, unable to think with abnormal thinking, and he doesn't know what abnormal thinking is.

And Lu Siyu... but it seemed that they could see through what they thought effortlessly.

Just like this time, he just felt that this family was not right, but he didn't know what was wrong. All of this looked completely different in Lu Siyu's eyes. When he said that, Song Wen suddenly thought It passed: "Do you think that gas poisoning was not an accident?"

Lu Siyu murmured.

Song Wen got up and said, "Is it an accident? We'll know by asking."

Lu Siyu was taken aback, "You want to check this?"

The resolute and resolute Song team took the initiative to help him pick up the bag: "It's all here, at least to hear what the person said, let's go to Lin Wanwan's house to kill a carbine."

The case has been found here, and there is only one step left to find the truth.
